Abstract: A method and an apparatus for waking up a WUR terminal in a wireless network are disclosed. The method includes: A radio access point sends a group identifier to at least one WUR terminal; and sends a WUR wake-up packet including a group identifier of a target group, to attempt to wake up all WUR terminals in the target group.

Abstract: A wireless access point, a terminal device, and a method for waking up a terminal device by a wireless access point. The terminal device includes a primary radio frequency circuit and a wake-up radio (WUR) radio frequency circuit. The WUR radio frequency circuit only receives a radio signal and operates on a specified channel. If the WUR radio frequency circuit receives a wake-up frame on the specified channel and the terminal device is a to-be-woken-up terminal device, the WUR radio frequency circuit wakes up the primary radio frequency circuit. The wake-up frame includes an identifier of the to-be-woken-up terminal device. The primary radio frequency circuit operates on an operating channel of the primary radio frequency circuit after being woken up.

Abstract: Methods, devices, and systems for registering and discovering a service. An access point (AP) may receive and maintain service information registered by an associated station (STA), and serve as a proxy for a STA to discover service information in a network, and further discover a direct association service and manage direct communication between STAs, thereby meeting a user's demand of selecting a network according to a service requirement.

Abstract: A method for handover between distributed access points (APs), where the method includes a central AP sending a first instruction to an AP 2. The first instruction includes an identifier of the wireless terminal, and the first instruction is used to instruct the AP 2 to start receiving a data frame from the wireless terminal, and forbid the AP 2 to return an acknowledgement frame to the wireless terminal. The central AP sends a handover success notification message to an AP 1 and the AP 2. The handover success notification message includes the identifier of the wireless terminal, and the handover success notification message is used to instruct the AP 1 to stop receiving the data frame from the wireless terminal, and is used to instruct the AP 2 to return the acknowledgement frame to the wireless terminal.

Abstract: A method, a network adapter, a host system, and a network device for implementing a network adapter offload function. If a data packet received by the network adapter or the host system is a data packet unknown to the network adapter, the data packet unknown to the network adapter is parsed, a new policy entry is generated, and the new policy entry is updated into the host policy table and the network adapter policy table. Therefore, for a packet that includes a new proprietary or standard protocol header Tag, only a functional module that parses the packet needs to be updated, so that the functional module is capable of processing such a packet and delivering a new policy entry to the host policy table and the network adapter policy table and the network adapter does not need to be changed.

Abstract: A method for implementing a VOIP call in a cloud computing environment and relates to the VOIP call field. By using an RDP proxy to implement bidirectional transmission of voice streams between a cloud desktop client and a communication peer end, and further implement a VOIP call, a communication delay and load of a cloud desktop virtual machine are reduced. The method is used for a VOIP call in a cloud computing environment.
